Definitions
- the invention relates to a method for producing a built camshaft and a device for carrying out the method.
- the object of the present invention is to provide a method for producing built camshafts, by means of which the pushing on of the cams onto the corresponding shaft is improved.
- This object is achieved by a method for producing a built camshaft, which is characterized by the features of claim 1.
- a joining device for carrying out this method has the features of claim 10.
- the main advantage of the present invention is that pushing the individual cams onto the shaft is made considerably easier by a front wedge-shaped lubricant groove or chamfer as seen in the area of the inner bore of the cam in the push-on direction, because lubricant introduced into this lubricant groove as a result of the wedge-shaped
- the design of the groove is continuously drawn into the inner bore of the groove during the push-on process, so that the friction between the outer periphery of the shaft and the inner periphery of the inner bore of the groove is considerably reduced.
- a cam can be rotated relatively easily into the predetermined circumferential position when pushed onto the shaft due to the aforementioned lubrication by the wedge-shaped groove.
- further lubricant grooves are provided on the inside of the cam, and not symmetrically to the central plane of the cam.
- the design of the wedge-shaped lubricant grooves is optimal.
- FIG. 1 is a finished camshaft manufactured
- FIG. 2 shows a section through a cam designed according to the invention
- Figure 3 is a view of the cam of Figure 2 in the Aufschub ⁇ chtung seen from the front;
- Figure 4 shows the arrangement of a cam on a fixing area of the shaft, which has a diameter that is larger than the diameter of the remaining areas of the shaft and
- FIG. 1 shows a built-up camshaft, which comprises a shaft 1, on which cams 2 are slid into predetermined axial positions, for example in slide-open direction A.
- the individual cams 2 of the built-up camshaft are also arranged in predetermined positions when viewed in the circumferential direction of the shaft 1.
- cams used in connection with the method according to the invention seen in the sliding-on direction A, have at least one wedge-shaped and ring-shaped in the region of their front side 23
- the slope can be straight or curved.
- one or more further grooves 22 can be provided. However, these are not arranged symmetrically to the longitudinal center plane of the cam 2, but rather to Front 23 of the same oriented.
- the lubricant grooves 22 can have the same shape or can be undercut in terms of the angle of the slope or the width of the grooves.
- the lubricant groove 22 fulfills two different functions. On the one hand, during the slide-on operation, a lubricant is introduced, which during the slide-on operation due to the wedge-shaped nature of the lubricant groove 22 is continuously drawn inwards to the inner circumference of the inner bore 21 of the cam 2, so that the inner surface of the inner bore 21 is lubricated during the entire slide-on process is, so that the cam 2 in ⁇ er Aufschiebe ⁇ chtung A with reduced friction on the shaft 1 can be moved to the predetermined axial position.
- the lubrication mentioned also ensures that the cam 2 can be rotated before the displacement to its predetermined axial position, during this displacement or after reaching its axial position m in the circumferential direction of the shaft 1 until it reaches its predetermined circumferential position.
- a lubricant is preferably used which is treated after the arrangement of all the cams 2 in the predetermined axial positions and the predetermined circumferential positions, that its friction-reducing effect is canceled.
- this is done by heating the built-up camshaft, the desired friction-reducing effect occurring when the lubricant is heated.
- the lubricant groove 22 also ensures that the cams 2 are automatically centered when placed on the circumference of the shaft 1. This is particularly important if the cams according to FIG.
- the lubricant grooves 22 of the cams 2 each serve as centering aids.
- these can have so-called ramps 11, in particular on their sides facing the cams 2 in the direction of extension A.
- rollers 31 ⁇ Arranged above the rollers 31 symmetrically to the above-mentioned symmetry line S of the cam 2 so that they abut the straight side surfaces of the cam 2. If the rollers 31 ⁇ are now printed evenly in the direction of the arrows P against the rectilinear side surfaces of the cam 2 by a device (not shown), this has the consequence that the cam 2 n aligns the holding part 30 exactly in the position shown, in which its line of symmetry S lies exactly on the line of symmetry of the opposing rollers 31, 31 and 31 31 ⁇ .
- an axial bearing is arranged in the holding plate 2, which can absorb the axial pushing-on force of the holding plate 30 and can be transmitted to the cam 2 and which has depressions 32 arranged on a circular arc, in which are preferably arranged balls 33, which are supported on the one hand on the bottom of the depressions 32 and on the other hand on the rear side 24 of the cam 2 opposite the front side 23.
- the described joining device is used as follows. First, a cam 2 of the type described above is arranged in the holding part 30 and removed. tet. The shaft 1 is then displaced with respect to the holding part 30 or the holding part 30 with respect to the shaft 1 such that the end of the inner bore 21 of the cam 2 facing the cam 2 reaches the end of the shaft 1. In the following, the aforementioned relative movement between the cam 2 and the shaft 1 shifts the cam 2 to its predetermined axial position, the lubrication being carried out by the lubricant introduced into the groove (s) 22 to facilitate the shift.
- the above-described rotation of the cam 2 m in the circumferential direction preferably takes place before the axial relative movement between cam 2 and shaft 1.
- cams but also other parts, such as, for example, thrust bearing rings, angle sensors, end pieces, etc., can be attached to the shaft 1 by the method described above and with the joining device explained above, these parts being what the As far as joints are concerned, they are designed in exactly the same way as cams 2.
- the present method can also be carried out in such a way that the joining device comprises a plurality of holding parts 30, in each of which cams are held in predetermined axial positions and in predetermined circumferential positions.
- the cams 2 held in such a joining device can then be pushed as a whole onto a shaft 1, or alternatively the shaft 1 m can be pushed into such a joining device and into the cams 2 held therein. All cams 2 then reach their axial positions and their circumferential positions on shaft 1 in good time.
